High alumina bricks symbolize a specialized class of refractory components engineered to withstand Severe temperatures exceeding 1,790°C though maintaining structural integrity and chemical security. These bricks possess high refractoriness, fantastic thermal shock resistance, and remarkable mechanical power, making them perfect for withstanding Intense temperatures and severe operating disorders. The basic attribute that distinguishes high alumina bricks from standard fire bricks lies within their elevated alumina (Al2O3) material, ordinarily ranging from forty five% to ninety%, which immediately correlates with their Increased functionality abilities.
Deliver us your furnace sort, running temperature, and amount—we’ll assist you end up picking the best high alumina brick Answer for your needs.
In production, the thermal shock resistance of refractory bricks is often enhanced by strengthening the particle construction traits of firebricks or adding a specific volume of synthetic cordierite (2Mg0.2AI203.5Si0z) as well as other minerals during the batching

In relation to high-temperature environments, picking out the suitable refractory substance is very important. High alumina bricks are Amongst the most responsible and greatly made use of materials in industries that demand from customers exceptional heat resistance and longevity.
5. The thermal shock resistance of your high alumina refractory brick is worse than that of your clay high alumina clay brick, that's intently connected with the mineral composition in the refractory brick. The high alumina brick, such as I, II grade is even worse compared to the III quality high alumina brick.
A Resco sales representative or marketplace applications professional will help you find the appropriate alumina brick for your personal application.
The substitution of fireclay stopper rods and pouring nozzles with high-alumina (Al₂O�?>seventy five%) variations has absolutely prevented molten steel breakthrough incidents in continual casting functions.
Requesting samples and browsing the plant (or verifying via video clip) is highly recommended for bulk discounts.
Great Corrosion Resistance: The high alumina content of our bricks offers outstanding resistance to chemical attacks from acids, alkalis, as well as other corrosive substances, ensuring prolonged support existence and minimum downtime.
Iron and Steel Industry: Perfect for blast furnaces, sizzling blast stoves, and ladles because of their great thermal balance and resistance to slag erosion.

Recently, its high temperature creep is calculated to replicate its high temperature construction energy. The exam final results clearly show that the refractoriness below load greater with the rise of Al2O3 content material.
By comprehension your requirements and selecting the suitable bricks, you can improve the efficiency and longevity of the products.
